Last week, the singer announced her partnership with Starbucks to promote the coffee chain’s latest permanent menu item, the “Cloud Macchiato” — espresso mixed with cold, whipped foam and topped with caramel or cinnamon.

And while it may sound delicious to sweet-tooth coffee lovers, the drink has left many of Grande’s fans feeling, at best, confused and at worst, betrayed.

The star, who has spoken publicly about being vegan, promoted the Cloud Macchiato on Twitter with photos of her in a signature Starbucks green apron playing with dogs — leading many to assume that the franchise’s newest addition would be vegan.

Grande, 25, even included the hashtag “#trythesoyversion.”

But, it turns out, the drink isn’t vegan at all — even with soy milk. That’s because the foam contains egg whites and the caramel syrup contains cream.

Now, vegan fans are saying “Thank u, Next” to the iced beverage and questioning whether or not Grande is even still vegan.

“Not sure why you would be an ambassador for this particular drink if you’re vegan,” one user tweeted. “Would have been nice to see you use your influence for a plant based food option or a drink that can be made vegan.”

Another wrote: “I thought Starbucks new drink since it’s being endorsed by Ariana Grande would be able to be made vegan since you know she IS vegan, but upon research it has egg white powder in. V(ery) sad.”

In a 2014 interview with the Mirror, Grande said that she sticks to a plant-based diet.

“It is tricky dining out, but I just stick to what I know — veggies, fruit and salad — then when I get home I’ll have something else,” she said.

However, some Arianators have come to the defense of the songstress.

“[She’s] definitely NOT in charge of what goes into the drink,” one user said.

Meanwhile Starbucks recently tweeted that while the Grande-endorsed drink doesn’t have a vegan alternative, the coffee chain still has plenty of plant-based beverages.
